Common Questions about Lactulose


How fast does lactulose make you poop?

It can take 24-48 hours for you to have a bowel movement, i.e., poop after taking lactulose.



Is lactulose just sugar water?

Lactulose is a synthetic form of two naturally occurring sugars, galactose and fructose. However, it is not digested and absorbed by the body like other sugars. When lactulose reaches the colon (large intestine), it draws water into the colon and makes stool softer.



Which is better: Miralax or lactulose?

Studies comparing Miralax (polyethylene glycol) and lactulose have found that Miralax is better in people with chronic constipation in terms of stool frequency, stool form, relief from stomach pain, and a reduced need for additional products.



Is it okay to take lactulose every day?

You should take lactulose for a few days at a time to treat occasional constipation. Taking this medication long-term can put you at risk of fluid and electrolyte imbalances. Talk to your doctor if you have chronic constipation that requires regular use of laxatives.



What is the best time to take lactulose?

If you are taking lactulose for constipation, you should take it at night before going to bed. If you are taking lactulose for liver disease, your doctor may ask you to take it 3-4 times a day.
